Helios

In ancient Greek religion and mythology, Helios (; ; Homeric Greek: ) is the god who personifies the Sun. His name is also Latinized as Helius, and he is often given the epithets Hyperion ("the one above") and Phaethon ("the shining"). Helios is often depicted in art with a radiant crown and driving a horse-drawn chariot through the sky. He was a guardian of oaths and also the god of sight. Though Helios was a relatively minor deity in Classical Greece, his worship grew more prominent in late antiquity thanks to his identification with several major solar divinities of the Roman period, particularly Apollo and Sol. The Roman Emperor Julian made Helios the central divinity of his short-lived revival of traditional Roman religious practices in the 4th century AD.

Helios figures prominently in several works of Greek mythology, poetry, and literature, in which he is often described as the son of the Titans Hyperion and Theia and brother of the goddesses Selene (the Moon) and Eos (the Dawn). Helios's most notable role in Greek mythology is the story of his mortal son Phaethon. In the Homeric epics, his most notable role is the one he plays in the Odyssey, where Odysseus's men despite his warnings impiously kill and eat Helios's sacred cattle that the god kept at Thrinacia, his sacred island. Once informed of their misdeed, Helios, in wrath, asks Zeus to punish those who wronged him, and Zeus, agreeing, strikes their ship with a thunderbolt, killing everyone except Odysseus himself, the only one who had not harmed the cattle and was allowed to live.
